Abstract

With trends shifting towards automation and labour saving in the production process in industry, testing and sorting steps associated with visual inspection are still often handled manually by human operators. Although human vision has many superior capabilities, however, its most significant shortcoming is the lack of continuity, and variability existing on an individual basis. Furthermore, manually inspecting and sorting samples is difficult and tiring for human operators.

Abstract

An integrated sensor with three elements (zinc oxide, tin oxide and tungsten oxide) was fabricated by thick film techniques in order to develop a smell sensor. Using this sensor and pattern recognition method, the possibility of identifying 15 chemical compounds which belong to the alcohol, ester, ketone, benzene and hydrocarbon group was examined. The following results were obtained: All 15 compounds have different patterns, so they can be individually identified; compounds which have the same functional groups have similar patterns; and, when gas sensitivity of three elements is displayed in a three‐dimensional space, the compounds with the same functional group form a specific closed space. This indicates that the sensor can identify functional groups of chemical compounds.

Abstract

Thick film thermistors based on the thermistor powder of the sintered ceramic thermistor, prepared from oxides of nickel, cobalt and manganese, were fabricated and studied. The ingredient compositions, including the composition proportions, influenced the properties of thick film thermistors. The effects of the compositions of the sintered ceramic thermistors, the amounts of additives used and the compositions of the glass binders on the properties of the thick film thermistors were also studied.

Abstract

This article proposes principles for reforming English adult social care by drawing on the experiences of other countries. These illustrate how the funding, organisation and delivery of services could be reformed, and shed light on the potential political and social factors affecting implementation of reforms.Reforms in other countries are commonly driven by the desire to develop and/or maintain universal access to social care. Formerly fragmented, un‐co‐ordinated and locally variable arrangements are being replaced with universal schemes, with national eligibility arrangements applicable to everyone regardless of age or ability to pay. Cash payments (personal budgets etc) instead of services in kind are widely used. However, such options can have different aims, including supporting family carers and stimulating local provider markets, as well as offering ‘consumer’ choice. Policies for family carers are usually integral to overall long‐term care arrangements. Finally, even in federal systems like Germany, Austria, Spain and Australia, central governments play a crucial role in ensuring universal, equitable and sustainable social care. Central government leadership: maximises risk pooling; enhances budgetary control mechanisms; safeguards equity and quality control; and provides political legitimacy.

Abstract

Purpose

Aims to focus on temperature sensors.

Design/methodology/approach

Negative temperature co‐efficient thermistor powders of ternary Mn, Co, Ni oxide along with RuO2 synthesized at relatively moderates temperature (1,000°C). Thick film thermistor paste compositions were formulated by mixing the semiconducting oxide powder, glass frit and organic vehicle. The physico‐chemical analysis, viz. X‐ray diffraction, scanning electron microscopy and thermogravimetry and IR spectroscopy were carried out for the synthesized powder and the resultant thick films. The X‐ray analysis of the powders showed the cubic spinel structure. The electrical properties like thermistor constant, sensitivity index and activation energy of the thick film NTC thermistor were determined.

Findings

The room temperature resistance is observed to range from 490 KΩ to 4.13 MΩ with thermistor constant ranging from 3,275 to 3,980 K, in the temperature range of 25‐300°C.

Originality/value

Describes research work on temperature sensors that are used for monitoring and control in many fields such as in home appliances, manufacturing industries, biomedical and automobile industries.

Abstract

Purpose

The purpose of this paper is to explore progress in electronic circuit miniaturisation, and study the new medical sensor devices emerging.

Design/methodology/approach

Circuit packaging advances in the mobile phone sector are examined. The products and expertise of a leading producer of non‐contact sensors and medical implants are described, followed by a series of medical applications of 3D circuitry.

Findings

Mobile phone enhancements are driving innovations in electronics that are transferable to other industries. Wafer‐thinning and 3D interconnection techniques shrink complex circuitry, enabling the construction of sensitive intelligent wireless sensors. Biologically inert packaging enables such devices to be implanted in the human body to improve sight and hearing, and monitor bone‐healing after surgery.

Originality/value

The paper shows how electronic packaging innovations are spinning out into non‐contact sensors and medical implants and will be of interest to engineers in these fields, and of general interest to a wider readership.

Abstract

Through the use of silicon‐on‐silicon packaging, VLSI chips can be interconnected by dense contacts and very fine conductor lines. Electrical and thermal properties obtained by means of this technique are discussed. The fabrication of small cooling channels in the silicon substrate and the application of the anodic bonding technique for chip mounting are demonstrated.

Abstract

The paper presents a comparative analysis of the properties of ruthenate resistor layers produced on alumina substrates and on dielectric layers previously deposited on them. The effect of dielectric type and the peak firing temperature of ruthenate layers upon the value of their resistance and TCR (temperature coefficient of resistance) has been investigated. The reproducibility and stability of these parameters have been evaluated.
